The lifetime of the photon increased in the whispering gallery


Physics from the University of Rennes I set a new record lifetime of a photon in the resonator. For this purpose, the authors have created a whispering gallery of “slowing down” of light material. As a result, the light quanta were held in the cavity about 2.5 millisecond — 25 times more than previous record-holder material. This result may find application in optical memory cells for photonic computers.
